Value Byte Format: The following table outlines the resulting data format of the value option
you send: (The unused bits of the transfer in nibbles (X in 0XXXNNNN) are sent with the
information at the relevant positions of the SysEx strings. If you want to transfer these deleted
bits, you need to enter zeros in the SysEx string.)
Value option Result
Auto The value is sent as one byte if the value range
maximum is 127 or less. If the maximum is higher
than 127, the value is sent as two bytes, the MSB (most
significant byte) first.
One Byte The value is sent as one byte.
MSB/LSB The value is sent in two bytes, with the MSB (most
significant byte) first.
LSB/MSB The value is sent in two bytes, with the LSB (least
significant byte) first.
BCD 4 LSB The value is sent as Binary Coded Decimal in four
bytes, in the order 1, 10, 100, 1000.
BCD 4 MSB The value is sent as Binary Coded Decimal in four
bytes, in the order 1000, 100, 10, 1.
2 Nibbles L The value is sent in two nibbles, with the least
significant nibble first.
3 Nibbles L The value is sent in three nibbles, with the least
significant nibble first.
4 Nibbles L The value is sent in four nibbles, with the least
significant nibble first.
2 Nibbles M The value is sent in two nibbles, with the most
significant nibble first.
3 Nibbles M The value is sent in three nibbles, with the most
significant nibble first.
4 Nibbles M The value is sent in four nibbles, with the most
significant nibble first.
2 ASCII M The value is sent in two nibbles, the most significant
nibble first; the nibbles are sent in ASCII format for
the hex value. For example, the value $7F (= 127 in
decimal) will be transmitted as a 7 and F.
3 ASCII M Same as 2 ASCII M, but in 3 nibbles.
4 ASCII M Same as 2 ASCII M, but in 4 nibbles.
